Electronic display technology or ePaper Displays can mimic the look of paper on a device’s display. Makes EPDs or ePaper displays popular Amazon Kindle. The bi-static nature of this display technology allows it to be used on devices that do not have a power budget. LCD. Recently, news has been received about this Apples Plan to use EPD Folding technology IPhone And IPad. Here we will discuss how EPDs work and how they can help improve these displays IoT Application
How does EPD work?
ePaper displays or EPDs are equipped with small capsules filled with charged ink particles that use the same ink as in the traditional printing industry. When properly charged, EPDs produce highly detailed images with contrasting proportions and readability of printed material.
How is EPD different from traditional LCD?
As discussed above, these displays have a bi-static nature. A bi-static display, also known as a Zero Power Display, has a unique feature that allows an image to stay on the display indefinitely without being refreshed. However, it is essential to refresh the screen on a traditional LCD – both an active matrix display like a TFT LCD and a passive matrix display like a monochromatic LCD. EPDs consume energy only when the screen is refreshed where reflected LCDs use energy to place images on the screen.
How can EPDs help advance IoT?
Thanks to the display’s bi-stable feature, EPDs can work with extremely low power inputs. Once the EPD text and image have been rendered, no additional power is required to maintain the image displayed on these displays. ePaper displays operate on so little power that extra power can be gathered to update. This extra power enables RFID or use NFC Device with batteryless EPD.
EPDs can be used to improve many IoT applications – logistics, manufacturing and retail. Manufacturers can combine these slim, light, high-read ePaper displays with highly power-restricted devices.
EPDs can be wirelessly attached to electronic shelf labels at retail locations. This will allow remote or central management to adjust prices for dynamic pricing strategies.
ePapers can also improve the logistics and manufacturing applications of IoT devices as it provides visibility into RFID / NFC tag data at a glance.
In addition, EPDs can improve the usability of a number of battery-powered IoT devices, such as utility meters, cold-chain temperature data loggers, and environmental sensors.
Other benefits of using EPD
Some of the advantages of using ePaper display are – very low power consumption, bi-stable property and NFC / RFID power-harvesting capability mentioned above. In addition to these, EPDs serve other purposes. These displays also offer high readability on the outside which makes it a suitable display technology Ebook Purpose EPDs can also be used on devices that have a slim and lightweight form factor, which is one of the reasons Apple uses these displays on foldable iPhones and iPads. In addition, manufacturers are offering the ePaper Display in three colors for testing with their device displays.
